A spinner has 10 10 ​equal-sized sections. Six Six of the sections are purple purple. a. What is the probability that the spinne
borishaifa [10]

Answer:

P(Spinner lands on purple section) = 0.6 = 60%

Step-by-step explanation:

We are given the following in the question:

Number of sections = 10

Number of purple sections = 6

\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}

a) probability that the spinner will land on purple purple

P(purple) =

=\dfrac{6}{10} = 0.6

0.6 is the probability that the spinner will land on purple purple.

b) Interpretation of probability

0.6\times 100\% = 60\%

There is a 60% chance that the spinner will land on purple color.

Write an exponential growth function, and then describe a real-world situation that the function could represent. Do the same fo
Irina18 [472]

Answer:

Step-by-step explanation:

Exponential growth function can be represented as follows

y = e^{bt}

Here y increases exponentially with respect to t . As t increases , rate at which y increases is increases .or

dy / dt =by , or rate of increase depends upon y itself

dy / y = bdt

integrating on both sides

lny = bt

y = e^{bt}

It represents very fast increase in y .

The unrestricted growth of population of human being is an example of exponential growth . As population increases , rate of growth of population also increases.

For exponential decay function

y = e^{-bt}

The decay of   a radioactive material is an example of exponential decay function.

6/10 + 20/100 = 8/10
TiliK225 [7]

6/10 can be simplified but we don't need to worry about it right now. We only need to worry about simplifying 20/100:

20/100 → 10/50 → 5/25 → 1/5

Find common denominators

1/5 → 2/10

6/10

Now, add.

6/10 + 2/10 = 8/10

Therefore, the equation is true.

Best of Luck!

After 15 years mary age will be fourtimes of her present age find her present age​
aliina [53]
Her present age would be 5 because 4m=m+5 which would then turn into 3m=15 because you would subtract the m from both sides and end up with 3m+15, then you would divide 3 to both sides which would then give u an answer of m=5
